Stopper for bottles

Abstract

Stopper for bottles, comprising a pouring element ( 1 ) assembled with a hinged closing cap ( 2 ), the closing cap ( 2 ) being able to be placed in an open position and a closed position, characterized in that said closing cap ( 2 ) comprises a protrusion ( 3 ) in its closest part to the pouring element ( 1 ), whose protrusion ( 3 ) contacts the pouring element ( 1 ) in the open position of the closing cap ( 2 ).

What is claimed is: 
     
       1. A stopper for bottles, comprising:
 a pouring element ( 1 ) which is attachable to the neck of a bottle; and 
 a closing cap ( 2 ) which is equipped with a protrusion ( 3 ) and which is connected to said pouring element ( 1 ) by way of a hinge ( 4 ); 
 wherein said stopper is transformable between an open configuration and a closed configuration; and 
 wherein said protrusion ( 3 ) is disposed adjacent to, and in contact with, said pouring element ( 1 ) when said stopper is in said open configuration; 
 wherein said pouring element is equipped with a nozzle ( 10 ), wherein said closing cap ( 2 ) comprises a closing collar ( 8 ) which is engaged to said nozzle ( 10 ) when said stopper is in said closed configuration, and wherein said closing collar ( 8 ) is equipped with a recess ( 9 ) which accommodates said protrusion when said stopper is in said closed configuration. 
 
     
     
       2. The stopper of  claim 1 , wherein said protrusion ( 3 ) is semicircular in shape in a cross-sectional plane taken along its longitudinal axis. 
     
     
       3. The stopper of  claim 1 , wherein said protrusion ( 3 ) is flexible. 
     
     
       4. The stopper of  claim 2 , wherein said protrusion ( 3 ) is flexible. 
     
     
       5. The stopper of  claim 1 , wherein the protrusion ( 3 ) is circumscribed within a circle defined in the pouring element ( 1 ). 
     
     
       6. The stopper of  claim 2 , wherein the protrusion ( 3 ) is circumscribed within a circle defined in the pouring element ( 1 ). 
     
     
       7. The stopper of  claim 3 , wherein the protrusion ( 3 ) is circumscribed within a circle defined in the pouring element ( 1 ). 
     
     
       8. The stopper of  claim 4 , wherein the protrusion ( 3 ) is circumscribed within a circle defined in the pouring element ( 1 ). 
     
     
       9. The stopper of  claim 1 , wherein said hinge ( 4 ) includes first and second arms ( 5 ), and wherein said protrusion ( 3 ) is disposed between said first and second arms ( 5 ). 
     
     
       10. The stopper of  claim 1 , wherein said closing cap ( 2 ) comprises a cavity ( 6 ) which is disposed next to said protrusion ( 3 ) when said stopper is in said closed configuration. 
     
     
       11. The stopper of  claim 1 , wherein said pouring element ( 1 ) comprises at least one lateral flange ( 7 ) projecting from said pouring element ( 1 ). 
     
     
       12. The stopper of  claim 1 , wherein the closing cap ( 2 ) comprises a cantilevered cover ( 11 ), comprising a plurality of ribs ( 12 ) at its lower part. 
     
     
       13. The stopper of  claim 1 , in combination with a bottle.
